What is Sanjago?

Sanjago is a dried bulb from an orchid called Cremastra appendiculata. The part used is the pseudobulb, the swollen base of the stem.

In Korean herbal medicine it is used in small amounts. A trained practitioner gives it for lumps, swollen glands, boils and skin sores that will not heal.

It is also made into a paste for the skin. That paste is used on sores, snake bites and insect bites.

Lab teams have looked at one of its compounds. They studied how it affects the growth of blood vessels. That work has not moved into people.

The honest verdict: no human trials back this herb. It is a long-standing East Asian remedy. Long use tells you what people have done for hundreds of years, but it is not proof that the herb works.

One point matters more than any other on this page. Bulbs sold under this market name can be the wrong plant. Some look-alike bulbs hold colchicine, a strong gout drug that has killed people in overdose.

Never buy this herb loose, online, or from a seller you cannot name.

How does Sanjago work?

No one has shown how Sanjago acts in the body. Any account of it is a best guess.

Korean and Chinese texts call it a cool, slightly toxic herb. They say it "clears heat" and "breaks up lumps". In plain terms, it was picked for hot, swollen, hard or pus-filled problems.

The bulb holds a compound called cremastranone. In lab tests it slows the growth of new blood vessels. That has been seen in cells and in animals.

That is worth noting. But cell and animal results often fail to hold up in people. Here they have not been tested in people at all.

What forms does Sanjago come in?

Sanjago is sold and used in a few simple forms:

- Dried sliced bulb, simmered with other herbs into a decoction (a strong tea) - Powdered bulb, made into pills or added to a formula by a practitioner - A wet skin paste, made from the powdered bulb, used on boils and sores - Rarely, as one small part of a packaged Korean or Chinese herbal formula

It is almost never used on its own. In most countries it is not sold as a standard capsule or tablet.

Where it comes from:

Sanjago is used in Korean herbal practice. It also appears in older East Asian medical writing, where the Chinese name is shan ci gu. Records go back several hundred years.

Old texts used it in a narrow, steady way. It was given for swollen neck glands, hard lumps, boils, sores that would not close, and bites.

It was valued as a strong, cooling herb. It was used for a short time, not as a daily tonic.

What does Sanjago help with?

• Boils and skin abscesses (pus-filled lumps): This is the classic use. Korean practice applies the powdered bulb as a paste, or adds the herb to a short internal formula, to bring a hot swollen boil to a head. There are no human trials. If a boil is spreading, hot to touch, or comes with fever, that needs a doctor, not a poultice.
• Scrofula (swollen lymph nodes in the neck, often linked to TB): Old texts list Sanjago among the herbs for hard, chained neck lumps. This was a named traditional use long before the cause of the disease was known. Today, swollen neck glands that last more than a few weeks need testing. Tuberculosis and lymphoma (a cancer of the lymph system) both need real treatment, and herbs do not replace it.
• Hard lumps and swellings under the skin: Traditional use here is strong; evidence is absent. The herb was said to "soften hardness". Some lab work on cremastranone has been used to promote the herb for tumours. That is not supported. No human trial has tested Sanjago for any growth or tumour, and any lump should be checked by a doctor.
• Snake and insect bites (traditional skin use): Folk use was to mash the bulb and lay it on the bite. This is history, not first aid. A venomous snake bite is a medical emergency. Call emergency services and go to hospital.
• Sore throat with swelling: Some formulas use small amounts for a hot, swollen, painful throat. This is a minor traditional use with no trial support. A throat that closes your airway, makes drooling or breathing hard, or comes with a high fever needs urgent care.

Which foods are rich in Sanjago?

Do not treat this as a food or a tea to drink for wellness; it is a short-term practitioner herb.

What are the side effects of Sanjago?

• Nausea
• Vomiting
• Stomach pain
• Diarrhoea
• Dry or irritated mouth and throat
• Skin rash or itching where the paste was applied
• Severe poisoning if the bulb is the wrong plant and holds colchicine (a strong gout drug)

Good to know:

Mild stomach upset is the effect most often reported in traditional practice, and the herb's own tradition treats it as slightly toxic.

The serious risk is not the herb itself but the supply. Bulbs sold under the same market name can be a different plant that contains colchicine. Colchicine poisoning starts with heavy vomiting and diarrhoea hours after a dose, then damages the blood, kidneys and heart, and it has killed people.

Because of that, treat any severe vomiting or diarrhoea after taking this herb as an emergency.

How much Sanjago should you take?

• Recommended daily: There is no dose proven safe and useful in people, because no human trial has been run. Classical East Asian texts give roughly 3 to 6 grams of the dried bulb per day, simmered as part of a mixed formula. Some sources give less. This herb is treated as slightly toxic in its own tradition, so it is a practitioner-only herb, not a self-care herb. For skin use, the powder is mixed with water or vinegar into a paste and laid on the sore area.
• Best time of day: When it is used, a decoction is usually split into two doses, morning and evening. No timing has been tested.
• With or without food: Taken after food, which is the usual East Asian practice for cooling or harsh herbs and may reduce stomach upset.
• Time to effect: Unknown. Traditional practice expected some change in a swelling within a few days to two weeks. There is no measured figure.
• How long to take it: Traditional use is short: days to a few weeks for an active swelling, not months. If nothing has changed after about a week, stop and see a doctor. Do not keep taking it in the hope that longer will work.
